About product
The SEERXtreme Series 18,000 BTU Mini Split Heat Pump excels in large living rooms, open floor plans, family rooms, or master suites up to 1,250 sq. ft., delivering powerful ductless cooling and extreme cold-weather heating down to -15°F for year-round reliability in harsh climates.
This ENERGY STAR-certified 1.5-ton unit provides 18,000 BTU cooling and 18,200 BTU heating via advanced inverter technology with 25 SEER2/10.5 HSPF2 ratings for up to 30% energy savings over standard systems. Seven modes (heat, cool, dry, fan, auto, sleep, ECO), 4 fan speeds, 765 CFM airflow, and 81 pints/day dehumidification offer versatile comfort from 60°F to 90°F, with quiet 28-50 dB indoor operation and a 24-hour timer.
Extreme low-temperature performance uses chassis electrical heating and auto-defrost for dependable operation to -15°F, paired with 135°F self-cleaning to eliminate mold and bacteria. WiFi app control, Alexa voice commands, and remote access enable smart scheduling, while R32 refrigerant ensures eco-efficiency. Pre-charged outdoor unit, full 13 ft installation kit on 208-230V power, ETL/AHRI certifications, and 8-year compressor warranty guarantee durable, low-maintenance performance.

90 productsWith summer temperatures rising 2.1°F since 1970 and energy costs climbing 13% annually, selecting the right air conditioning system affects both your monthly budget and home value.
Homeowners can choose between central systems, mini-splits, or portable units, while renters face lease restrictions. Window units require no permanent modifications, making them ideal for apartments. Mini-splits offer superior efficiency but need property owner consent.
Calculate cooling load using 20 BTU per square foot, then add 10% for high ceilings or poor insulation to prevent undersizing and premature failure.
| System Type | Cooling Capacity | Energy Efficiency | Upfront Cost | Best For |
|---|---|---|---|---|
| Window AC | 5,000-24,000 BTU | 8-12 EER | $150-$800 | Single rooms, renters |
| Portable AC | 8,000-18,000 BTU | 6-10 EER | $300-$900 | Temporary cooling |
| Mini-Split | 9,000-48,000 BTU | 16-22 SEER | $1,500-$8,000 | Zone cooling |
| Central AC | 18,000-60,000 BTU | 13-20 SEER | $3,000-$15,000 | Whole-home comfort |
Modern mini-splits achieve SEER ratings above 20, nearly double the efficiency of older central systems.
Operating costs depend on system efficiency, local electricity rates, and usage patterns. At the national average of $0.13 per kWh, running a 10,000 BTU window unit 8 hours daily costs $95 monthly, while an equivalent mini-split costs only $52 due to superior efficiency.
| Daily Usage | Window AC (10 EER) | Mini-Split (18 SEER) | Central AC (14 SEER) |
|---|---|---|---|
| 8 hours | $62/month | $52/month | $158/month |
| 12 hours | $93/month | $78/month | $237/month |
Dirty filters reduce airflow by 50%, forcing systems to work harder. Window units and portables need monthly filter cleaning, while central systems require filter replacement every 30-90 days.
Outdoor condenser coils accumulate debris that reduces efficiency by 30% within three years if neglected. Annual professional cleaning costs $150-200 but restores 5-15% efficiency loss.
Humidity affects comfort and system selection. Oversized systems cycle rapidly without adequate dehumidification, creating discomfort despite proper temperature control. Variable-speed mini-splits excel in humid climates through precise humidity control.
In humid regions, size systems for humidity removal rather than temperature reduction. Properly sized units running continuously outperform oversized units cycling frequently.
WiFi connectivity enables remote control and adds $50-150 to system cost. Real value comes from usage monitoring and maintenance alerts that prevent costly repairs.
Programmable thermostats reduce energy consumption 10-15% through automatic temperature adjustments during unoccupied periods.
Local building codes often require electrical permits for 240V connections needed by larger units and mini-splits. Permit costs range from $50-200 but ensure safe installation.
HOA restrictions may prohibit visible outdoor equipment. Review covenants before purchasing to avoid installation delays or fines.
🏠 For Renters
Window units and portable systems offer mobility without permanent modifications. Focus on energy efficiency to minimize utility costs.
🏡 For Homeowners
Mini-split and central systems provide long-term value through superior efficiency and increased property value.
💡 Key Decision Factor
Consider your five-year housing situation when making this investment for optimal value.
Air conditioner selection balances upfront cost, operating expenses, and installation constraints. Renters benefit from efficient window units or portable systems. Homeowners should prioritize mini-split or central systems for long-term value and superior efficiency. Consider your five-year housing situation when making this investment.
